Using Reaper DAW and Session percussionist. It seems the play/stop/record in Reaper is not linked to playback in Percussionist. So I can't start Percussionist when I hit play/record in Reaper. I have an existing mix and two instances of Percussionist on two different tracks. I want to play the three parts synchronised. Manually pressing play of each of course creates extreme offsets! Am I missing a setting for Reaper play/rec to trigger Percussionist?
